Every Destiny expansion brings with it new materials and consumable items, and Rise of Iron is no different.

Largely themed around the game's new enemy factions - SIVA and Splicers - these allow you to access new areas in Patrol areas, play activities and earn new items, so it's worth knowing how to get them easily and what exactly they can do.

Splicer keys are one of the more common, and more useful, materials introduced in Rise of Iron. They are used to:

Access certain areas in the Plaguelands guarded by lasers, such as starting the Ghallarhorn Exotic Quest

In Archeon's Forge, to re-enter the arena if you revive yourself

While it appears you can get them from all kinds of Splicer enemies in the game (we even seemingly got one from killing one of the red, stationary SIVA 'nodes&#39 there is a very high chance one will drop when killing a Brood Mother.

These are Wizards that populate The Plaguelands; there's one in the Lords' Watch area, to the right of where you spawn; two are in Giant's Husk, to the side of the ship under the container area, a couple in The Archeon's Forge, and likely others elsewhere too. In short, just have an explore and you're bound to bump into one sooner than later.

Some say their high drop rate is a glitch, but we've had other things drop from them (such as a Splicer Intel Relay), and it makes sense a powerful enemy will give you a decent reoccurring drop - but we'll see how this develops in future patches.

Note that though you can only old 10 Splicer Keys at once time, you can store 10 in your Vault and 10 on each character, too, potentially allowing a total of 40 in your possession.

Skeleton Key locations, use explained

These are Strike-specific materials that you can spend at the end of Heroic Strikes to get their unique item, rather than leaving it entirely up to chance. Here's how you get them:

One from completing the None are Perfect Quest line (complete Sepiks Perfected Strike)

Possible drop from completing Strikes in Rise of Iron

In short, the more Strikes you play in Rise of Iron, the more likely this will drop; it's rumoured that running Strike playlists will increase your chances, but seemingly no evidence to support this yet.

Splicer Intel Relay locations, use explained

Splicer Intel Relays come in several different types - all under the same name - but all appear to have the same function - to access certain areas in The Plaguelands, such as the starting Cosmodrome area with the Ketch for the Khvostov schematic for the Khvostov 7G-OX Exotic Quest.

These are dropped by Brood Mothers throughout The Plaguelands (see the Splicer Key section above for examples of where they appear) but seem to be a rarer drop than Splicer Keys.

There might be more of a use for these in certain situations than just accessing the starting Cosmodrome, and we'll update this article if that's the case.

SIVA Offerings locations, use explained

These are used to start the Archon's Forge event within the Plaguelands, and come in three different varieties, each one increasing the difficulty of the event you will face:

Fused SIVA Offering - Common (green), 320 Light recommended

Enhanced SIVA Offering - Uncommon (blue), 340 Light recommended

Perfected SIVA Offering - Rare (purple), 360 Light recommended

Strangely, only SIVA Offering can be held in your inventory at one time, though you can swap them to different characters or to the Vault to collect more.

Unlike Splicer Keys or Splicer Intel Relay, it seems that these can drop from any enemy you come across in The Plaguelands, so do some Patrols and get killing foes until one appears in your inventory. Again, since you can only hold one at a time, give it to another character or deposit in the Vault straight away, so you always have one waiting if you need to participate in Archon's Forge quickly.
